I would if I had an E-M1. Affordable decent size FF camera is what I was looking for. Until now there was only the 7000 Euros Leica M. Now the A7 is a wonderful alternative. Because let's get completely honest: FF IQ is way beyond of what a m43 sensor can possibly give. Two desirable lenses for A7 at this time, in my opinion: Zeiss 35mm f2.8 and 52mm f1.4 respectively. I hope that soon we will get a 85mm f1.2/f1.4 or so. Did I mention there are superb Zeiss lenses we are talking about when we say A7?
